Title: Method and apparatus for quantitatively determining the degree of agglutination of particles
Inventor: YAMAMOTO HIROSHI
IPC: G01N15/06
Filed: 1981-06-10
Abstract: A method and an apparatus is disclosed for quantitatively determining the degree of agglutination of a suspension of particles or the existence of agglutination of the latter. A liquid containing agglutinated lumps or a substance or substances which are about to agglutinate is made to pass slowly through a small tube. In this process, agglutinated lumps and unagglutinated particles are separated from one another in the liquid. The degree of agglutination of particles and the concentration of the substance to be tested by this means can be determined quantitatively by finding the difference in the optical properties both of the accumulated layer of agglutinated lumps and of the suspended layer of unagglutinated particles, or from the change in the optical properties of one or other of the two abovementioned layers, in particular the suspended layer.

Title: Method and device for testing and defect detection in operation of electrical and/or electronic display devices
Inventor: BECKER MANFRED
IPC: G06F11/00
Filed: 1981-06-26
Abstract: A method and device for testing and defect detection during operation of electrical and/or electronic display devices, especially of 7-segment displays. The connections of all the display elements, which form the 7-segment displays, are joined together on one side and are connected to the power supply lead via a measurement resistor, the measurement resistor being bridged during normal display operation by short-circuiting a semiconductor switching element, and being connected in the power supply lead to the display elements during a defect detection process. During a defect detection process, only a single display element is driven for a short period of time by a central control logic circuit, and the measurement resistor signal, which is proportional to the current, is compared with a nominal value which has tolerances. It is possible by shifting in time the period of time for which the switch which is in parallel with the measurement resistor is open, likewise to test the hardware groups of the display device.

Title: Hygienic device for toilets
Inventor: LUTZ RALPH DR ING
IPC: A47K13/30
Filed: 1981-07-15
Abstract: A hygienic device for toilets is specified, in particular for public toilets in the form of WCs which have a toilet bowl with a seat surface. The hygienic device (10) is arranged with spacing above a toilet bowl (12) and consists essentially of a hygienic additional seat (22) which can be extended from a housing (20) into a position above the normal seat surface (18). Provided in the housing (20) is a disinfecting apparatus (38, 40, 46) which disinfects the additional seat (22) before it is extended in each case so that, when the release (42) is actuated, firstly the disinfecting operation proceeds and then the additional seat (22) is extended from the housing (20). Furthermore, a return apparatus (54) is provided for the additional seat (22), which apparatus ensures automatic retraction of the additional seat (22) into the housing (20) when the additional seat (22) is no longer loaded by the weight of the user. The additional seat (22) itself consists of self-supporting plastic with a smooth, non-porous surface, the material being unaffected by disinfectants. A hygienic device of this type for toilets is a guarantee to the user that there is absolutely no risk of infection; additionally, the otherwise prevalent aversion to public toilets is thus diminished to a great extent. <IMAGE>

Title: Anti-noise hood for typewriters and automatic printing or recording units
Inventor: DRYGALSKI REINHART VON DR
IPC: B41J29/08
Filed: 1981-12-31
Abstract: Automatic printing (e.g. teleprinter-capable) typewriters cannot overcome the nuisance of airborne sound. Known remedial measures are ear protectors, underlays, housings, adjustable walls or wall coatings. Novel: pivotable hoods all round at a distance from the printing unit, that is to say independent of individual, environment and machine. The hood traps the noise as a lampshade does light. It is lowered by hand over the noise source; especially during print-out, but possibly also during the inputting of texts; in this case the keyboard is left free, being provided with a viewing glass and an aperture for the emergence of paper. The hood is suspended above the machine or rests on it. It can be used for any machine. It is attached so as to be removable and vertically adjustable; by means of a pull-down device suspended from the ceiling or from a type of whip-like lamp pedestal which is attached to the surface of the table; it is better if the hood folds by means of hinges which are connected to the table surface by means of screw clamps. The drawing shows a recent model with viewing window and aperture for the emergence of paper which can be placed on the machine while leaving the keyboard free. <IMAGE>
Patent DE-3201247-A1 (DE)
Title: Strain fitting for double-insulator strings
Inventor: HILGARTH GUENTHER PROF DR ING
IPC: H02G7/20
Filed: 1982-01-16
Abstract: A strain fitting for double-insulator strings (1, 2) for high-voltage overhead lines has a rigid frame (9) which spaces the insulator strings (1, 2) apart and has two upper connecting points (10, 11) for the two insulator strings and one or more lower connecting points (14) for a conductor cable or conductor harness. In the event of a fracture of an insulator string there is a risk of the other insulator string also fracturing as a result of the excessive lateral load. The invention is based on the object of creating a strain fitting for double-insulator strings, in which the kinematics which prevent lateral forces in the event of fracture of an insulator string are of compact and robust construction, and in which direct impingement of the strain fitting on the healthy insulator is reliably prevented even in the event of excessively severe vibrations. To this end, it is provided according to the invention that the frame (9) consist of a plate (12), that the centre of gravity (S) of the plate (12) lie above the connecting line (V) between the two upper connecting points (10, 11), and that the plate (12) be connected to the insulator strings (1, 2) via hinged straps (5, 7) which can pivot parallel to the plane of the frame and which enclose the centre of gravity (S) between them. <IMAGE>
Patent DE-3204472-A1 (DE)
Title: Rotary bending machine
Inventor: PRUEMMER ROLF DR ING
IPC: G01N3/34
Filed: 1982-02-09
Abstract: The rotary bending machine comprises a drive spindle which is rotatably mounted in a fixed bearing block and has a clamping device for the end of a specimen to be tested for its fatigue strength under reverse bending stresses. The other end is clamped in a loading bearing on which a force which produces a bending moment in the specimen acts via a lever arm. To decouple the loading from the intrinsic weight of the loading bearing, the force which produces the loading bending moment acts on the associated lever arm of the loading bearing in a horizontal plane which extends through the axis of rotation. The intrinsic weight of the loading bearing is absorbed by a supporting bearing having horizontal mobility, for example as a result of one or more horizontal sliding surfaces. Two equally large, parallel loading forces are able to act via one lever arm in each case in the opposite direction so that no axial force is exerted on the specimen. To produce a specified loading bending moment, a loading force parallel to the axis can be produced by dimensioning the lever arm. At that end of the specimen which is remote from the drive shaft, a braking device can be provided to make it possible to produce a torsional stress in the specimen in addition to the bending stress.

Title: Acceleration limit-value switch
Inventor: NOLLE WINFRIED ING GRAD
IPC: H01H35/14
Filed: 1982-09-04
Abstract: The acceleration limit-value switch is provided for motor vehicles and has an inertia body which is seated on a bed and is held in a quiescent position by magnetic forces. Said forces are exerted by a permanent magnet which is provided in the underneath of the inertia body and acts on an iron part. There is a defined air gap between the permanent magnet and the iron part. In consequence, the magnetic force can be set very precisely, so that the critical acceleration or deceleration value at which the inertia body is deflected can be set exactly. The defined air gap also prevents contamination influence.
